Making Metals

We have probably all carried out the reduction of Copper Oxide using Carbon at some time, maybe to show the reactivity series or maybe to talk about redox. I was wondering though if this could be used as a quantitative IA lab, 'Calculate the % Yield of Copper Produced From The Reduction of Copper Oxide With Carbon? (To assess DCP and CEv maybe?)   If one knows the mass of Copper Oxide, one should be able to calculate the theoretical mass of ...
